Thank you for your reply to my last question. I found this opisthobranch at Shima. This opisthobranch crawled on rock with seaweed like my photo.
Could you please identify this animal for me.
Location: Shima Pref. Mie Japan (Kii Peninsula east coast)
Water temperature: 13C
Date Jan. 2000
Crawling on rock

[Note added April 29 2005: See message #13442 suggesting this may be Favorinus perfoliatus]
I'm not sure of this one but I wonder if it is a colour form of Favorinus mirabilis. It has the dark spot on the cerata and black perfoliate rhinophores like that species but without an idea of its anatomy it could easily be something else.
